Intelligent Gyro Compass (iGC)
An invaluable heading and motion sensor for ROV and AUV navigation applications
The Tritech Intelligent Gyro Compass (iGC) combines three angular rate gyros with three orthogonal DC accelerometers and three orthogonal magnetometers. This makes the iGC an invaluable heading sensor and Motion Reference Unit (MRU) for numerous ROV and AUV navigation applications. The iGC can operate as a stand-alone device or be further enhanced by using alongside the Tritech Intelligent Fibre-Optic Gyro (iFG).
The Intelligent Gyro Compass (iGC) provides essential movement data not available from widely used magnetically slaved gyro and flux gate compasses.
Designed in a compact 4000m depth rated housing the iGC incorporates a 9 sensor orientation processor, a proprietary interface and protocol converter.
Operating over the full 360° of angular motion on three axes, the iGC provides orientation matrix and quaternion formats. These may be used directly, but are normally converted to an industry standard navigation output telegram. This can be configured by the user to match a number of common heading sensors.
